We're dividing 50741816 by 686 
We want to divide 50741816 by 686.

Step 1:
5 divided by 686 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 686

Going ahead to step 2:
When dividing 50 by 686, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (7) from the dividend, attach it to 50 and continue: 507 / 686

Let's proceed to step 3:
When dividing 507 by 686, we get 0 with a remainder of 507.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 507 to get 507.
Grab the next digit (4) from the dividend, add it to 507, then carry on: 5074 / 686

On to step 4:
The number 686 fits into 5074 7 times, leaving a remainder of 272.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 4802 from 5074, we get 272.
Bring next digit (1) of the dividend behind the 272 and repeat the process: 2721 / 686

Going ahead to step 5:
If we divide 2721 by 686, we get 3 and a remainder of 663.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 663 after subtracting 2058 from 2721.
Bring next digit (8) of the dividend behind the 663 and repeat the process: 6638 / 686

Going ahead to step 6:
When dividing 6638 by 686, we get 9 with a remainder of 464.
The number 9 becomes the next digit in our result. 
Result so far: 739.0
Subtract 6174 from 6638 to get 464.
Bring next digit (1) of the dividend behind the 464 and repeat the process: 4641 / 686

On to step 7:
When dividing 4641 by 686, we get 6 with a remainder of 525.
The number 6 becomes the next digit in our result. 
Result so far: 7396.0
If we take 4116 away from 4641, we end up with 525.
Append the next digit (6) from the dividend to 525 and continue with: 5256 / 686

Going ahead to step 8:
When dividing 5256 by 686, we get 7 with a remainder of 454.
Put 7 as the next digit of the answer. 
Result so far: 73967.0
Subtract 4802 from 5256 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 9:
When dividing 4540 by 686, we get 6 with a remainder of 424.
Write down 6 as next digit of the result. 
Result so far: 73967.6
If we subtract 4116 from 4540, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 10:
When dividing 4240 by 686, we get 6 with a remainder of 124.
The next digit of our result is 6. 
Result so far: 73967.66
The remainder is 124 after subtracting 4116 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 73967.66 with a remainder of 0.124.
